System And Method For Utilizing Transformer Wasted Energy With Modular Co2 Capture Systems

Abstract: A system of using thermal energy in the form of wasted heat of a transformer to minimize required energy for CO2 Direct Air Capture (DAC) operation comprising a heat transfer unit configured to be coupled to a transformer and receiv wasted heat in the form of hot insulating liquid, and configured to be coupled to one or more CO2 DAC modules including CO2 adsorbent or absorbent medium to transfer wasted heat from the hot insulating liquid in the heat transfer unit to the one or more CO2 DAC modules where the transferred heat is used to heat the CO2 adsorbent or absorbent medium to minimize requid energy for CO2 DAC operation.
